Subject: Re: Compile new kernel for 5200B w/ ELDK
Hi Albrecht,
please excuse a probably really dumb question about compiling a new =20
kernel for a Freescale 5200B using the ELDK 4=2E2=2E=2E=2E
I am playing with a Lite5200B eval board=2E The software coming from =20
Freescale, including an older kernel (2=2E6=2E16=2E11-rt18), works fine=
=2E
I installed ELDK 4=2E2 on a FC box, and first compiled u-boot 1=2E3=2E4=
=2E =20
Wrote it to flash, and it works nicely afaict=2E
Then I compiled the 2=2E6=2E24=2E2 kernel coming with the ELDK, using the=
=20
commands "make ARCH=3Dpowerpc CROSS_COMPILE=3Dppc_6xx- lite5200_defconfig
; =20
make ARCH=3Dpowerpc CROSS_COMPILE=3Dppc_6xx- uImage"=2E The kernel=
loads, =20
decompresses, but then there is no output any more after
"Uncompressing =20
Kernel Image =2E=2E=2E OK"=2E The u-boot environment contains (quoted=
from =20
printenv) "bootargs=3Dconsole=3DttyPSC0,115200 root=3D/dev/mtdblock0 rw =
=20
rootfstype=3Djffs2 verbose" (and, again, the Freescale kernel is not =20
silent)=2E
I found a message which stated that I should include
<snip>
chosen {
linux,stdout-path =3D "/soc5200@f0000000/serial@2000";
};
</snip>
in the file arch/powerpc/boot/dts/lite5200=2Edts=2E Recompiled, but =20
without success=2E I believe it's a minor tweak I need to add, but I =20
don't have a clue what=2E Unfortunately neither the wiki nor Google
gave =20
answers=2E Can anyone enlighten me??
Use a recent kernel version=2E 2=2E6=2E26 should work out of the box=
without
too much hassle=2E Some of the older versions had problems effectively
stalling Linux very early without any output on the console=2E
Do not put any more effort in such an old kernel=2E
Cheers
Detlev
